8 Features of the AMCCall Setup TimeThe call setup time when using the AMC is slightly longer than when using thenative application, because the call is set up via the call manager (AMCC) inthe enterprise network. If the AMC is registered over the cellular network thecall setup time is usually less then 10 seconds. If the phone does not haveaccess to data the call setup is done via DTMF which usual takes approx.10-20 seconds.8.2 Accepting CallsAMC calls can be accepted like all other calls by pressing the concerned key . Whichcalls are intercepted by the AMC is governed by the 12.7 setting.Caller IDThe AMC for Android supports the transmission of Caller IDs ("see who’scalling") via the AMCC. To make use of this possibility, and to not be subjectto different policies regarding the transmission of Caller IDs of the differentproviders, the following settings have to be applied:1. Packet Data has to be set to GPRS Dynamic or Local Network; refer to12.6.2. The MTC Number has to be set on the AMC if the operator does notinclude the original Caller ID in the signaling. For the Caller ID transmis-sion to work properly the MTC Number has to match 100%, a matchingprefix is not enough; refer to 12.1.4.8.3 Emergency CallsEmergency calls have to be placed as direct calls, i.e. not with the AMC.This is done automatically for the major emergency numbers such as 112 and 911.Local emergency numbers that have to be dialed directly can be specified as ExceptionNumbers. Refer to 12.1.7 on page 47.amc-4_android_ug_en_2014-03 24
